Unmengen an Lösungsvarianten, ständige Erweiterungen und übersichtliche Funktionen, das ist beim lösen von Geocaches DIE App die ich immer gesucht habe. Nervig ist alleine die immer wieder aufkommende Frage zum Texteinfügen aus dem Zwischenspeicher, aber das ist jammern auf hohem Niveau. Bin sehr zufrieden damit! ### 5/5 — Prima Tool *2025-03-16* Ich nutze das Tool gerne und bei einer so klasse Arbeit ist auch der Kauf als Wertschätzung drin. An die Sortierung muss ich mich noch gewöhnen. Danke für die Arbeit. ### 5/5 — Unschlagbare Sammlung *2024-12-18* Lieber Mark, einfach klasse. Vielen Dank! Langes1010 ### 5/5 — Absolute Empfehlung *2024-08-14* Selten so eine umfangreiche und gute App gesehen! Hier spendiere ich gern einen Kaffee! ### 1/5 — RIP OFF! *2023-06-03* If you wanted a donation , make it clear ! I was under the impression I was purchasing a service . After I paid $9.99 I was informed you had a free version . I want a refund ### 5/5 — Ein wunderbar hilfreiches Tool *2023-02-12* Ich nutze diese Toolsammlung schon recht lange und sie hilft mir zuverlässig. Die Bedienung ist nicht immer direkt so einfach zu verstehen, aber wenn man sich ein wenig damit beschäftigt fluppt es. Ich bin froh so eine hilfreiche App für das Geocachen gefunden zu haben und habe sehr gerne die goldene Version bezahlt. Weiter so! ### 5/5 — Geniale App *2021-08-22* GC Wizard ist eine tolle App, die nicht nur beim Lösen von Mysterys unverzichtbar ist, sondern auf bei diversen Rätselspiel sehr hilfreich ist. Die Möglichkeiten, die diese App bietet, sind scheinbar unendlich. Vielen Dank für diese geniale App ### 5/5 — Useful App! *2020-11-01* Lass dir den Kaffee schmecken! ## Frequently asked questions about GC Wizard Gold ### What is GC Wizard Gold?
